In case you thought that part of that higher ticket price you pay for seeing a 3-D movie goes to pay for the glasses required to see the often poorly done, post-production 3-D effects, you’re mistaken. It’s the studios behind these big-budget cash-ins that have been footing the bill, but that could all change in the next year.

Someone over at 3D glasses manufacturer RealD must have sat next to a child during a 3D movie and grimaced as the little tyke strained to keep the too-big-and-heavy glasses on his nose for half an hour, then finally gave up and suffered through the rest of the film in blurry 2D. The company started making glasses that fit on kids’ faces.
